did a group-ICA on the basis of all subjects from both groups, and then run dual-regression. You then did a two-group t-test using the spatial maps output by dual-regression, and found a significant difference for one of the RSNs. However, what does it mean if the voxels showing a ...

(self-)selection processes, violating the exogeneity assumption of regression analysis, thereby leading to a problem of endogeneity. This is especially true for dual qualifiers diverted by family background from higher education to their first educational pathway into VET. Moreover, these first ...
Multiple regression with ROIs significant in bivariate correlations identified the right middle frontal gyrus (p ¼ 0.004) and the right cerebellar Crus I (p ¼ 0.003) as significant independent predictors of performance over the remaining ROIs (p ¼ 0.90 for left cerebellar Crus I; p ¼...
Another potential limitation is the possibility of regression to the mean. In some studies, participants with dual decline had higher baseline gait speed and memory performance than usual agers. Participants with dual decline who had higher baseline gait and memory may have had more room to decline...
we found significant correlations betweenΔinhibition in DT andΔgait variables in the corresponding DT conditions. Since visual inspection of regression slopes suggested the presence of outliers that might affect those correlations, a multiple regression analysis was conducted with theΔscores of interest...
In order to test this hypothesis, we fit a logistic regression model to predict objective stimulus category at the single-trial level based on pre-stimulus brain states and tested the model using a leave-one-out cross-validation scheme. We found that model discriminability for objective stimulus ...
Multivariate Cox regression models including factors possibly influencing OS/RFS in relation to MIF protein expression failed to exhibit significance, indicating that MIF is not an independent prognostic marker in breast cancer, probably due to its close relation to hormone receptor status (data not ...
